General: Type 1 diabetes is a variety of presentation of the Diabetes mellitus which represents 5 to 10% of all cases of diabetes in the general population, it has been called also Juvenile Diabetes, which is detected in childhood and adolescence. The age in which the diagnosis is made is variable and can range from the first year of life to 13 or 14 years of age. In rare cases it’s diagnosed in the first months of life. The term insulin-dependent, as it is also known to this disease is due to the same sources, this is secondary to the destruction of the pancreatic insulin-producing cells called beta cells. Such destruction in turn is acquired and is believed is secondary to the presence of (mainly viral) infections that attack the pancreas. The body to detect the causative organism of infection produces substances called antibodies to try to delete it. Unfortunately for unknown reasons, these antibodies in addition to attacking microorganisms infectious just also destroying its own cells (in this case of the pancreas), this process is called AUTOIMMUNITY. Diabetes mellitus type 1 is therefore a disease of autoimmune origin.
The above has resulted in the lack of insulin production in the body. Insulin as it is known is a hormone that is responsible for the introduction of glucose (sugar) in the cells so that these in turn can be used as energy for all metabolic processes. It is therefore easy to deduce that if this hormone is missing there is no who can enter the glucose cells remaining this blood increasingly higher levels which is the most important fact in a diabetic person (hyperglycemia). Been called to these patients insulin-dependent, because they depend on exogenous insulin (injected) to continue living. (Source: NYSE DNB). However this term has caused confusion in some people who associate it with the unit caused by drugs, including giving falsely insulin said caractermotivo whereby the insulin-dependent term is increasingly obsolete.
